Humans get fleas from dogs, especially in case of massive infestations. You typically find fleas on the feet, ankles, and lower legs because they can’t jump higher, but you can also find them in your hair. Clean your house regularly and kill the fleas on your dog to get rid of them.
Dogs become infested with fleas at least once in their lives. Only half of the dog owners realize their pet has fleas.
When dogs aren’t given antiparasitic substances for prevention, they can attract fleas from the garden, parks, other animals, or infested homes.
Signs of flea infestation in dogs include intense scratching, biting and excessive licking, inflammation of the skin, and hair loss.
But fleas aren’t just a pain for dogs. They can also infect humans.
In this article, you will learn how people get fleas from dogs, what flea bites look like on humans, what to do if you see fleas, and more.
How Can People Get Fleas from Dogs?
People can get fleas from heavily infested dogs. Fleas usually live on animals they prefer as their main host, such as dogs, but there are cases where they can accidentally parasitize humans. This is one of the reasons it is recommended to prevent flea infestations in pets.
People can get fleas from their dog in two ways:
Adult fleas rarely jump from one animal to another or from animal to human, but there are exceptions. This happens if you are in direct contact with an infected pet.
Fleas on a massively infested dog fall off into the environment, often your home or garden.
The most common places in the house where you can find eggs, larvae, pupae, or adult fleas are:
- Furniture (sofa, bed)
- Your dog’s bedding
- Cracks in the wall
Although fleas lay their eggs in your dog’s fur, they are not sticky and fall off easily. The larvae hatch from the eggs, feed, and enter the pupa stage. The adult flea comes out of the pupa, actively looking for food, and if you are in the area, it can infest you.
Can Fleas Get in Human Hair?
Although it is very rare for fleas to be found in human hair, it is possible. Fleas can find a good place in the human hair to take their next blood meal if there are no pets in the area to feed on. They feel much more protected in the human hair than on hairless areas of our body.
How to Get Rid of Fleas on Humans
Get rid of fleas with a bath. A bath is typically enough to get rid of the fleas on your body. You can wash your hair with regular shampoo and comb with it a thick comb if you have fleas in your hair.

Are Dogs’ Fleas Dangerous to Humans?
Fleas are considered dangerous to humans because they can transmit diseases or cause generalized allergic reactions, as they do to dogs. Fleas can transmit tapeworms, cat scratch disease, plague, and other diseases to humans.
Dog fleas usually don’t bite people, but it can happen. They can be dangerous and are considered a risk to human health. In addition to causing infections and irritations, fleas can spread diseases or cause life-threatening allergic reactions.
Allergic reactions to flea bites in humans are usually considered medical emergencies and are manifested by:
- Difficulty breathing (shortness of breath, wheezing)
- Swelling of the face, lips, and tongue
- Chest pain
The diseases transmitted to humans are the same as those transmitted in flea bites on dogs, being represented by:
Tungiasis: Caused by sand fleas (Tunga penetrans). The female flea burrows into the skin to lay eggs and causes pain and infection.
Tapeworms: Ctenocephalides felis fleas can be infested with tapeworm eggs. A person can get tapeworms if they swallow an infested flea.
Cat scratch disease: Ctenocephalides spp. fleas are responsible for transmitting the bacterium Bartonella spp. It is transmitted when infected flea feces come in contact with a lesion on the person’s body.
Plague: The plague-causing bacterium (Yersinia pestis) is transmitted when a person swallows a flea or comes in contact with its infected feces.
Typhus: Caused by Rickettsia typhi, a microorganism that is transmitted through the bite of an infected flea.
